In this paper we characterise the patterns of wildﬁre occurrence in 3 regions of northern Portugal, using selection ratio functions to evaluate the ﬁre proneness of different land cover and topographic categories. For attaining this objective we characterised 1382 wildﬁres larger than 5 ha, which occurred in the years 1990–1991, according to land cover (10 categories), slope (5 categories) and aspect (5 categories) within which they occurred. For each ﬁre, the use of the different land cover and topographic categories was compared with availability in a surrounding buffer. For land cover, ﬁre proneness was much higher in shrublands, whereas agricultural areas and agro-forestry systems where less likely to burn. In terms of slope, steep slopes were more prone to ﬁre. Differences in land cover in the different slope categories contributed to this result, although there was an overall slope effect on the ﬁre proneness of all land cover types. In terms of aspect, only ﬂat areas were less ﬁre prone. Finally, there were regional variations in land cover susceptibility to ﬁre, but these did not occur for slope or aspect. In terms of landscape planning these results suggest that the more effective fuel breaks should be implemented in areas with agricultural crops in ﬂat slopes</style></abstract><issue><style face="normal" font="default" size="100%">1-2</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;publisher: Elsevier B.V.</style></notes></record></records></xml>
